Since python 3, __ne__ is defined in terms of __eq__ by the default object class.

It looks like 2 classes in security.py and password.py define an __ne__ as:

   return not self.__eq__(other)

so these two defs can be removed.

The other instances define __ne__ in terms of cmp, return False or add isinstance()
checks before using != operator.
